Many countries like the United States have had over fishing crisis that have been resolved 1. Many countries such as Australia, Chile, Belize, Namibia, Denmark, and the United States, have faced similar problems but the fishing rights they have enforced have helped transform struggling fisheries. Which would be key for the lower status countries. 2. According to the Environmental Defense fund, “In the Gulf of Mexico, red snapper populations are three times what they were in 2007 when we helped reform that fishery” so if we use their methods many other countries might be able to re populate their fish.
Their presence in the ocean is usually seasonal, responding to the availability of prey, which is seasonal in most places, increasing with temperature and sunshine in the spring and summer (Dawson and Jacobs 2001). Jellyfish size ranges from 10cm to 3m and weighs around 200kg, their size already increase their habitat in the ocean which has become a problem for fishing companies. Secondly, jellyfish feed on anything they come across, it all depends on the structure of the jellyfish. This impact causes a reduction in the ocean species, because it is many jellyfish that needs to feed on something. Thirdly, human problems resulting from jellyfish blooms, Stings from pelagic cnidarians because discomfort and sometimes medical emergencies for swimmers and waders primarily in warm marine waters worldwide (reviewed in Fenner & Williamson 1996, Burnett 2001).
Question 1 Overfishing which occurs witch occurs when more fish are caught than the population can replace through natural reproduction. This has serious consequences that can affect not only the balance of life in the oceans but also the social and economic well-being of populations who depend on fish for their way of life. Overfishing in Freshwater Fishing is a crucial source of livelihood in developing nations where they can mostly fish inland and also as a main source of food that provided protein. Overfishing has lead to some freshwater fish to become extinct especially those that are found close to the surface of the water that are large and can be easily captured. The Mekong giant catfish, which is possibly the world’s largest freshwater fish, is seriously threatened by overfishing.
In my opinion, I believe that marine mammals should not be held in captivity for many reasons. To start, they are taking away the animals from their natural habitat. Secondly, captivity causes both major and minor health problems. Another significant reason is that the poor marine creatures do not have enough space to swim resulting in severe boredom and causing them to do harm to themselves Captivity causes many health problems for the innocent marine mammals. There was an incident when Six of Marineland 's seals were blinded, or got serious eye problems because of the unclean water.
this process by EPA does not grant the public the opportunity to be heard on whether the dumping will adverselty affect them but rather the public is reduced to mere spectators. Further, the Ocean Dumping Management Act has been challenged to clearly articulate the scope and benefits of the act, given shifts in the types of materials proposed for ocean disposal, multiple agencies involved in ocean dumping permitting, and reduced public attention to environmental and human health risks of ocean disposal. Conclusion Unless the act is reviewed so as to ensure the public participation and aim at balancing between the economic and environmental tradeoffs. The act will be a mere rhetoric which does not solve the real problem but rather burden the people it seeks to protect through unnecessary
Also, the ocean filters the air we breathe, and like said before, supplies 80% of the oxygen we breathe. Pollution causes the ocean not to function properly and oxygen levels can and will diminish. The ocean is also home to medicines that treat heart disease, cancer, and more. The plants or animals that give us these medicines are endangered as long as marine pollution exists. The remedies can be lost causing more people to die because of the lost medicines.
The primary objective should be to remove the Zebra mussels from the great lakes even though the had positive impacts, the zebra mussels don’t belong in this ecosystem. This objective would take time, but if people work together this could happen faster. Small acts such as draining all water from your boats and bait wells could help stop the Zebra Mussels to spread fast. The future is in question for the little zebra mussel as they produce rapidly and outcompete native species in the lake but hopefully we can control them in the
This is why captains are buckling down on the manatees manners. If they do not follow the rules, they will have their permit pulled away from the FWC to run their business. FWC has really cracked down on these rules and helped manatees tremendously. This is important not only to save these creatures, but our economy here in Crystal River. Even locals can avoid harassing the manatees, By slowing down and observing the manatees without harassing them.
As observations were conducted on multiple reefs, however, a major decline in the water quality and coral coverage of reefs worldwide had declined dramatically. It was upon these observations that the reefs ability to self sustain was questioned (P. Harris, 2012). Their structure is resilient to most natural disturbances, however, they are extremely vulnerable to human interference such as the nutrient contamination of their water quality that has occurred. The contamination this study focuses on is as a result of fertiliser and other nutrient rich pollution which have contaminated these coral sanctuaries. This contamination has lead to great loss of coral coverage.
This might have been because they were fighting each other, or fighting for the food source. The next interaction in the lake is between the Daphnia and the bass population. This is predator-prey because the Bass eat the Daphnia because the Daphnia is the food source for the bass. It is important for us to use other people from our groups data so that we can really figure out the main factors causing the bass population to decrease. Without my groups data I would have only been able to find evidence of overfishing, but with the data I received from the others I was able to find the bridge to the temperature issue.
The reading states that the pollution hypothesis seemed the more likely to cause the decline in the sea otter populations and provides three reasons of support. However, the professor states that the predation hypothesis is the most likely the cause of the sea otter decline in populations and refutes each of the others reasons. First, the reading states that the oil ridgs and other sources of industrial chemical pollution caused the death to the sea otters. The professor opposes this point by saying that the pollution theroy is weakened because people did not find dead sea otter on the beaches of the sea, and that supports the predation theory because if the sea otters were killed because of the pollution, they should wash up to the shores, and that did not happen.
91% of Hawaii is reliant on importing food and 92% on importing energy. So when the land deteriorates from impacts like incorrect waste disposal it creates even less space for natural resources. There are specific environmental challenges against Hawaii that include sea levels rising, global warming, food and water scarcity, land depletion, high energy costs and invasive species and natural disasters that bring more invasive species and kill natural resources and local species like coral. But by 2050 Hawaii should be revolved and more sustainable and have lasting sustainability. By 2030 70% of local energy will be
